I have a 1st generation 1JZ and it has a new PCV valve (part number 88402 5HW) and I bought an aftermarket one for the 2JZ (part number 045-0375) which looks completely different than the one in the car now. What I'm wondering is my car has NO rubber grommet in the valve cover. Do I need one? The 2JZ PCV valve seems to fit loosely in the valve cover compared to the one that's in it now, which leads me to think I need a grommet. If someone can chime in I'd really appreciate it. My car is smoking and I'm trying to knock off the cheap and easy stuff first (yes I know it might be the turbos...pulled downpipe off and no ash was present).
Thanks!
Thanks!
